A lightweight data field that displays SmO2 and tHb from the BSXinsight. 

Real-time muscle monitoring is provided via the ANT+ MO2 profile. If your device has enough available memory then we also record the SmO2 and tHb to the FIT file. (Newer Garmin devices should be fine for this.) You can now use the BSXinsight desktop app and mobile app to start the BSXinsight and download the data. Or, you can use this app to start/stop the BSXinsight and record the data to the Garmin's FIT file.
